Under Development - Ulduar

Ulduar is something Blizzard are going to introduce in Patch 3.1, this is going to be the most exciting update methinks in this patch, with lots of new things going into Ulduar. Here is a part of the page on Ulduar: [quote]Many players have already gotten their Wrath of the Lich King raiding feet wet in Naxxramas and the Sartharion raid, but Ulduar is the first example of the expansion's much larger, truly epic scope of raiding, as will be evident from the second you set foot in the instance. The most obvious difference between Ulduar and its predecessors is that the dungeon actually comprises two separate raid areas. The first section is an epic battle against a vast army standing between you and the entrance of the dungeon proper; in the second area, you will dive into the heart of the dungeon itself and finally discover the secrets of Ulduar. Of course, the vehicle gauntlet, the Iron Army, and the battle against the Flame Leviathan are only the start of World of Warcraft's most ambitious raid to date. Patch 3.1 will hit the Public Test Realms very soon, so you will be able to see for yourself what other challenges await beyond the gates of ancient Ulduar.
